SOLID MODELING

Introduction

Solid modeling is the set of rules or principles of computer and even the mathematical modeling of solids of three dimensions. The basics of CAD that isComputer Aided Designis the combination of the principles of solid modeling and geometry and this supports the animation, exchange, visualization and creation of models of objects which are physical.

As a part of computer designing, there are many difficult calculations about engineering which are carried out and solid modeling helps to make it easier.Solid Modeling Techniques was developed in the 70’s for designing the internal as well external parts of the computers. They were more widely used as they support calculations of properties of objects such as mass, volume etc.

Properties Of Solid Modeling

Solid ModelingTechniques was developed in the 1970’s as a medium to mainly design computers and polyhedral models, since they had the capacity to classify any point in an three dimensional figure, be it its internal or external point, solid modeling makes it very easy. This kind of representation also supports the calculations of different characteristics of the figure such as its weight, inertia, are and volume and solid modeling also can automatically generate meshes over the object or the image for analysis and correction. But this modeling is only limited to certain geometric shapes such as the sphere, cone etc.

Computer Aided Design

Geometric Modeling and Solid Modeling together forms the basis for Computer Aided Design.Neither the Geometric Modeling nor the Solid Modeling was alone capable of building had all the properties alone in them, hence a combination of both was used to design structures, which were indeed much better than the ones built with any one of them. These structures were actually giving birth to a new technique by adding the required traits of both Solid Modeling and Geometric Modeling. These new structures supported the geometry of the Geometric Modeling as well as the approximation and calculation properties of the Solid Modeling. Hence it has the traits of both, making the structures more flexible. It will be possible to make the exact structure that is required of any shape any perfect size, having geometrical properties also. These new type of Data Structures were called the B-Rep Solid Models.

Uses Of Solid Modeling In Surgical FieldModern Computer technology have taken over every field in today’s world. It has assisted the humans in every possible manner. Even in Surgical field, it is widely used:

· Projection of specific body parts using this technique and help surgeons in performing surgery.

· Visuals of body parts can also be made to teach and guide new surgeons.

· Analyze different process in body by making relevant graphics.

· Designing of new medical devices and machines.

Uses Of Solid Modeling For Entertainment

These days entertainment is a part of our life style. This solid modeling can also be widely used for this entertainment field. Laser shows, 3D movies, Cartoon films etc. Even creation of games is done by these techniques.
